Restoration of walking ability in stroke patients is the basis for their return to their families and society. Motor-cognitive dual-task training (MCDTT) can effectively strengthen the functional network connection between motor and cognitive brain regions and promote brain functional network remodeling, which is more relevant to daily life than single-task training in improving walking dysfunction of stroke patients and can more effectively train patients' adaptive walking ability. This paper summarizes the application and research progress of MCDTT in post-stroke walking rehabilitation, and aims to provide a theoretical basis for further research on systematic motor-cognitive therapy techniques to promote walking rehabilitation in stroke patients.
